PresbyMAX and standard LASIK both use lasers to reshape the cornea, but they aim for different visual outcomes. PresbyMAX targets both distance and near vision, while LASIK mainly sharpens distance focus.
Different visual goals
Conventional LASIK usually aims for clear distance vision in each treated eye. PresbyMAX creates a controlled multifocal surface so each eye has extended depth of focus.
- PresbyMAX is designed for people with presbyopia who struggle with near tasks
- LASIK suits younger patients or those happy to use reading glasses later
- PresbyMAX uses sophisticated profiles to balance distance, intermediate, and near
- Detailed testing checks corneal regularity and dominance before treatment
Adaptation and possible trade-offs
PresbyMAX demands more adaptation because it introduces multiple focus zones. Some patients notice mild compromises that standard LASIK does not create.
- Halos, glare, or reduced contrast can occur, especially at night
- Most adapt over weeks, but some still prefer glasses for specific tasks
- Standard LASIK often gives very crisp distance vision but limited near focus
- Contact lens trials of monovision or blended vision can help decision-making
